I would like to find out where to look for the application jar file that is being used in a WAS application. We have an EAR, WAR and then just deploy a jar file each time we make changes. The problem is we have two jar files, (created on different dates), in the same folder and need to find out what jar file is being picked up? Where do you look for this mapping? I have looked in the class path, and the deployment descriptor and there is no indication of what file is being use.
